AIMS We evaluated the relationship between the mitral inflow velocities by pulsed Doppler echocardiography and mitral annular motion velocities by pulsed Doppler tissue imaging in patients with mitral annular calcification. METHODS AND RESULTS Fifty-three patients with mitral annular calcification were divided into two groups: severe mitral annular calcification (n=15, mitral annular calcific...

FIG. 1. EOF of the zonal-mean surface pressure in the CKV model (solid), zonal mean of the nonzonally averaged surface pressure in the CKV model (dashed), and zonal mean of the sector EOF shown in CKV’s Fig. 11a (dotted–dashed). We thank Dr. Robinson for his comments (Robinson 2004). Robinson argues that the results of Cash et al. (2002, hereafter CKV) are not inconsistent with the presence of ...

In this study, nonlinear bending of solid and annular functionally graded (FG) sector plates subjected to transverse mechanical loading and thermal gradient along the thickness direction is investigated. Material properties are varied continuously along the plate thickness according to power-law distribution of the volume fraction of the constituents. According to von-Karman relation for large ...

A survey of the spatial and temporal behavior of the atmospheric general circulation as it relates to both polar regions is presented. The review is based on the European Centre for Medium-Range Weather Forecasts (ECMWF) 40-year reanalysis (ERA-40), updated using ECMWF operational analyses. The analysis spans 1960–2005 in the Northern Hemisphere, but is restricted to 1979–2005 in the Southern H...

INTRODUCTION Laparoscopic duodenal atresia repair is an advanced procedure performed in select pediatric surgical centers. Recently, sub-6mm endosurgical staplers have been introduced, facilitating and accelerating the creation of intracorporeal intestinal anastomoses. PRESENTATION OF CASE We performed a laparoscopic duodenojejunostomy in a one-day-old child with duodenal atresia due to annul...

In this paper, numerical investigation of upward two phase flow of air-water has been studied. Different conditions of flow regimes including annular, wispy annular, slug, churn and bubbly are simulated based on Hewitt and Roberts map, and a good agreement between the experimental data of the map and the numerical simulation has been observed. Accordingly, a proper CFD model in CFD software of ...
